Land Rover Prikbord

Weet iemand toevallig met welk aanhaalmoment je de bouten van de koppen vast zet voor een 90V8 3.5 carb uit 1989??

Uit het handboek voor revisie van de V8:

Cylinder head bolts:
Outer row 60 Nm . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
Centre row 90 Nm . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
Inner row 90 Nm . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

Succes ermee,

All pre 96 V8's with the 14 bolt heads (yes that's all of them) have this problem to some degree, Its not maybe causing a big problem (or so you think) but it is steadily killing of the detergent's in your Oil .

All post 96 Rover V8 engine's no longer have the outer 4 head bolts on each bank, this is what the engine has always needed, but took Rover 25 years to realize. The following solutions/actions are available to you.


Do Nothing, Well Rover got away with it for 25 years. Its a far off long term problem on new engines and an immediate problem on all pre 96 used medium to high mileage engines, of all assumed conditions.

Use conventional Tin (Shim Steel ) Gaskets "To retain compression ratio," This is actually better than it may seem, you can (we would ) refit the outer 4 offending bolts as Rover but torque them to only 20-25ft/lb. so they fill the hole but have no detrimental effect, this is generally the best option if your "Head and Block" faces are new or near perfect order



het hele verhaal staat op de site van RPI

het gaat volgens mij over het kromtrekken van de cilinderkop en daardoor
lekkage,dit heb ik nu ook

heeft iemand ervaring met bovenstaande oplossing?
